Actively take over main Switching Module Elementary Function.
As illustrated in fig. 1 and 2, the present invention proposes a kind of dual star topology redundant topology framework implementation method.Based on multiple-unit service
After device is as technique verification platform, including 2 power module units, 2 Switching Module units, 8 computing module units and 2
Insert modular unit.Wherein 2 Switching Module units are as system core main control unit, respectively as main and subordinate node；8 calculating moulds
The each unit of module unit includes 2 circuit-switched data accesses, 2 tunnels management access, is respectively connected to 2 Switching Module units, forms double star
Type frame structure.Meanwhile two are connected with 1 circuit-switched data access, 1 tunnel management access between crosspoint, realize 2 star-like accesses interconnection.
When normal work, only main Switching Module unit carries out data transmission and system mode management, once host node breaks down, from section
Point obtains host node malfunction, actively adapter tube master node functionality by data between two crosspoints and management access.
Whole system is divided by implementation method of the present invention using VPX framework multi-unit server as technique verification platform
Three common layer (Utility Plane), management level (Management Plane), data Layer (Data Plane) levels: public
Co-layer refers mainly to general shared signal, ﹢ 12V power supply etc., and management level are mainly IPMB supervisory control signals, and data Layer is mainly
SRIOX4 high speed data transfer signal.In the present invention, data Layer, management level are based on dual star topology redundant topology framework mode and carry out
Design, working method is similar, and embodiment explanation is carried out by taking data Layer as an example.
In data Layer, each computing module unit has 2 road SRIOX4 interfaces, respectively with 2 Switching Module cell S RIO
Switching path is connected, and data Layer double star configuration is formed on 2 Switching Module units.2 Switching Module hardware structures are complete
Just as different slot position replacements can be carried out, but operating mode has master-slave, exchanges based on the small default of slot number, slot number is big
Be defaulted as from exchange.Each Switching Module externally provides 10 road SRIOX4 interfaces, wherein 8 tunnels respectively with 8 computing module phases
Even, 1 tunnel with exchange after insert module be connected, 1 tunnel be used for two Switching Modules between interconnect, thus formation double star configuration whole

S101, main Switching Module unit insert modular unit after exchanging and receive external data；
S102, data are packaged by main Switching Module unit to be handled and is sent to computing module unit by data path；
The data received are handled and send back main Switching Module unit by S103, computing module unit；
The data transmission sent back is inserted modular unit to after exchanging and exported by S104, main Switching Module unit；
S105 breaks down in response to main Switching Module unit, monitors to lead from Switching Module unit by heartbeat mechanism
The fault message of Switching Module unit and the work for taking over main Switching Module unit.
As shown in figure 3, data insert module by outside after exchanging and enter main Switching Module unit, main friendship when working normally
Mold changing module unit is carried out being packaged processing and be sent to data, is sent to 8 computing module units by SRIO data path, is calculated
Modular unit handles the data received, is sent to main Switching Module unit after the completion of processing, and module is inserted after exchanging will
Data are transmitted to outside.In the process, though having connected from Switching Module unit data path, it is constantly in standby mode,
And continue to monitor main Switching Module health status.When the failure of main Switching Module unit, passes through principal and subordinate from Switching Module and exchange
Data path obtains main Switching Module fault message between module, actively takes over main Switching Module data transmission and sending function,
So that data transmission is unaffected, the highly-reliable transmission of data is realized, effectively prevent entire product function failure, data are lost
It loses.
Heartbeat mechanism refers to, can be by between two Switching Module units when main Switching Module unit works normally
SRIO access sends the low and high level signal of oneself definition, detects this kind of signal, the main interchange mode in surface from Switching Module unit
Module unit is working properly, when not receiving this kind of signal from Switching Module unit, then it is assumed that main Switching Module cell failure, then
The work of main Switching Module unit is taken over from Switching Module unit.
In one embodiment, main Switching Module unit slotting modular unit reception external data after exchanging includes:
Main Switching Module unit passes through high speed interconnection backboard unit and main Switching Module list via modular unit is inserted after exchange
The data path that member is formed receives external data.
In one embodiment, data are packaged by main Switching Module unit handles and is sent to meter by data path
Calculating modular unit includes:
Main Switching Module unit is handled the data packing that modular unit transmission comes is inserted after exchange, and via main exchange
Modular unit interconnects the data path that backboard unit and computing module unit are formed by high speed and is sent to computing module unit.
In one embodiment, the data received are handled and send back main Switching Module by computing module unit
Unit includes:
The data received from main Switching Module handle and via main Switching Module unit by computing module unit
The data path that backboard unit and computing module unit are formed, which is interconnected, by high speed sends back main Switching Module unit.
In one embodiment, main Switching Module unit will the data transmission that sent back to exchange after insert modular unit into
Row exports
The data that main Switching Module unit will be sent back from computing module unit pass through high speed via main Switching Module unit
Interconnection backboard unit with exchange after insert the data path that module is formed be sent to exchange after slotting modular unit exported.
In one embodiment, it breaks down in response to main Switching Module unit, passes through heartbeat from Switching Module unit
Mechanism monitors the fault message of main Switching Module unit and takes over the work of main Switching Module unit
Data path is formed from Switching Module unit by backboard unit and main Switching Module unit, and logical by data
Road monitors the fault condition of main Switching Module unit；
When main Switching Module unit operates normally, it is in standby from Switching Module unit；
It breaks down in response to main Switching Module unit, the work of main Switching Module unit is taken over from Switching Module unit.
From above-described embodiment as can be seen that dual star topology redundant topology architecture system provided in an embodiment of the present invention and framework are real
Existing method, once effectively prevent whole system disabler, number caused by single node star topology node device breaks down
According to the problem of loss, the realization of dual star topology redundant topology framework ensure that the highly-reliable transmission of data.
